A The fragmatome tip was inserted 1 cm beneath the fluid level (arrow); B A high-sensitivity infrared thermal camera was used to detect the temperature of the fragmatome tip at the fluid level (arrow) of the balanced salt solution. C The thermal imager revealed the temperature of the fragmatome tip at the fluid level (arrow) of the silicone oil. D The change in the temperature at the fragmatome tip in the balanced salt solution and silicone oil in 240 s
